SHADE-ROLLER.

Specification of Letters Patent.

Patented May-8, 1917.

Application filed October 21, 1916. Serial No. 126,818.

To all fio/wm t may concern Beit known that we, EMIL KnAnMi-iii andsliade-rollers, the object being to provide a shade-roller that can befitted to windowframes of different widths. ln other words, our improvedshade-roller includes a spindle which is adjustable longitudinally ofthe casing therefor, said 'casing beingin prac-` tice a shade-roller.'To arrange ourshades roller for window-frames of various sizes,

wardly, hence in order to attach the `shade` roller to'windowframes'of-'diifere'nt widths, it is but -necessary to adjust thelongitudinally movable spindle. ln yanother em`-' bodiinent'of ourinvention, the spindle may be `arranged to v-be forced` inwardly by thespring.7

We 'will now 'proceed to describe 'our 'inventi'onin detail,theessenti'al features' of* which will be summarized in the'appendedclaims, referencel beingv had to the acycoinp anying .draw-ing, formingpart hereof,

wherein:

li`ig.`7 is a fragmentary sectional detail` view, the'section beingtaken'on aline 7?-7 in Fig. 1. y

As herein embodied, our improved shades! roller consists offashade-carrying"casing7l extends longitudinallyl thereof for the"greater'part of its length, said clfaniber having in communication:vtherewith" a some what smaller bore or chamber-`9 to receive'A thevinner end of a spindle 10. The spindle'tt'-` 10 is herein illustrated astubular, but may be solid if desirable. The spindle 10, whether tubularor solid, is` provided=with longitudinal groovesll to be engaged bythepawls or dogs 12'whichfare' carried at@ plate 13 which is'loosely ttedto and sur` rounds the spindle 10.

To one end of the casing '7, w'e secure' a cap 14 which is carried' by aturned d'own'or reduced portion 15' ofthecasing7, pfrovidedl'T/ with'slots' 1S'to receive the ribs19'on; said cap, (see'Fig' 5).The'rib`s-19fare formed' by striking down al portionof'the wal-lofthe'cap y14 and serve astkeys lto engagefthe recesses QO'in the`p'awl-plate13, -whereby`-80 said plate is held againstl rotation;

As can'b'e'seen in Figql, the pla-teV 13 iis located in' the chamber 21,-foimed'byT the cap 14 and partlyins'ert'ed end 'of the casing" 7. Tokeep the plated?) in position we 'proiA 85 videl the side-wall ofthe cap14 with stops 22 laterally expanded-'from the oute'rends of the ribs'19(see'Fig. 3)'. f The plate 13'as shown b vdotted'linesin'Fig. 3lis'lo'c'a'tedA between'the stopsfQQand supplemental stops *'90 S22aonfthe capv (see dotted lineFig. 3), whereby longitudinal displacementf of"Y the plate 13 is prevented- The'plate'landfcap 14 arepro'vid'ed 'withflanges 24 land 25, rer* spectively, around f the" openings" therein',95=V through which the spindle' f 10 passe'sy'to"vl serve asfbearingsfor th'ef'spindl'eflO;

To effect an outwaidmovement ofthe spindle 10,when the'rollerlisremovedfrom the brackets QG and 27,: we providea fspringilOO 28, the springnormallyextendingthe` spin? dle outwardly, the ini'ier'iend'ofthe springbeing secured 'to thespindle'l() 'atQTthe outer 'end being' secured toth'eiplatfe 13.* To

securethe outer end'of'said spring to"said"105'-" plate, we provide`eyesZSa' (seeFigs.` Q'and I* 4) formedI f 'by'` striking out some ofthematerial of said plate. The free end"of"thel spring is'passedfthioughthe'fey'es 28a, and

clenched.

@ne end of the casing 7 carries a threaded adjustable trunnion 29,having a rounded portion 30 to engage the opening 31 in the bracket 27.The adjustable trunnion 29 permits the shade-roller to be centeredrelative to the Window-frame. The spring 28 may be arranged to normallyextend the spindle 10, or tonormally retract same. To adapt the spindle10 for engagement With the bracket 26, to prevent the prematureWithdrawal thereof, We may split the end thereof as at 47 a and expandor spread the split end to form yieldable projections 48a, which can beforced through the opening 32 in the bracket 26. The expanded end of thespindle 10 will prevent the premature witlr draival thereof when thespring 28 is arranged to normally retract the spindle 10. To prevent therotation of the spindle 10 when the casing is rotated, We provide thebracket 26 With projections 49a extending into the opening 32 to engagethe grooves 11 in the spindle 10 (see Fig. 7

When the casing 7 is rotated, the spring 28 Will be Wound up, andretained in a Wound up or partly Wound up condition by the pavvls ordogs 12 in the usual manner. To prevent the spindle 10 from being forcedtoo far outwardly, when the roller is removed from its brackets, Weprovide a stop pin 33 (Fig. 1) which Will strike the flange 24 on theplate 13 and limit the outward movement of the spindle 10.

In the form of our invention shown in Fig. 6, the casing 34 is providedWith a chamber 35 containing a spring 36 surrounding a spindle 37. Thespring 36 may be secured at one end thereof to the casing 34 at 38, theopposite end of the spring being secured to the spindle 37 at 39. Thespring 36 may be arranged to normally extend or to normally retract thespindle 37. The spindle 37 is provided with grooves 4() extendinglongitudinally thereof to be engaged by paWls mounted on a plate locatedin the cap 41. The cap plate and pavvls employed in this latterembodiment of our invention vvill be the same as illustrated in Fig. 1;hence, a detailed showing thereof has been omitted. In this latterembodiment of our invention We provide the outer end of the spindle 37With notches 42 to engage the side-Walls 43 of a javv in a bracket 44,to prevent the rotation of said spindle.

The opposite end of the casing 34 carries a cylindrical trunnion 45similar to the trunnion 30 in theform illustrated in Fig. 1, rotatablyengaging a bracket 46. 'Io adjust the roller to a Window-frame ofgreater Width than the roller is arranged for, the spindle 37 Will bemoved longitudinally of the easing and the notches 42 caused to engagethe bracket 44.
